I slept 10 hours in a row and woke up sleep stoned

Had a mega busy day yesterday editing a story that was so good I didn’t notice it was 7:00pm before I finished. Asleep by 9:15, I woke up at 7:00am. It’s been years since I slept 10 hours in a row! I dreamed I was on a boat and trying to find provisions in the galley to make lunch. All I could find were slabs of ribs, birthday cake and gin. I see why people wake up groggy after sleeping all night. I was still barely awake after I’d walked my one mile route. I’m used to waking up bright eyed and bushy tailed. Maybe that’s cuz I only surface sleep. I also see why folks gulp caffeine first thing and don’t want to be talked to until they’re not groggy. This reminds me what a drug coffee is, and most people take this drug every day.
